Rebirth and Return to Before Cheating on the Art Exam

My roommate plotted against me, which resulted in me breaking the rules on the art exam and being sentenced to cheating. Afterwards, she posted the test results online and guided netizens to commit cyber violence against me. I couldn't bear the humiliation and went to argue with my roommate, only to find that she was kissing my boyfriend passionately. When she saw me arriving, she laughed loudly: "Hey, isn't this the cheating sister? You targeted me in every possible way, and now your retribution has come." Later, the cheating incident became a big issue, and my reputation was ruined. I was stabbed to death in the street by an angry candidate in the same class. When I opened my eyes again, I went back to the day before the art exam.
